He's a sociology major at USC. His mother is from Barbados and he likes calypso music. While suspended in 2004, he trained daily at a Hollywood boxing gym with trainer Freddie Roach, who worked with Mike Tyson.

He earned 2001 Parade All-American, Super Prep All-American, Prep Star All-American, Tom Lemming All-American, Max Emfinger All-American, Super Prep Elite 50, Prep Star Dream Team, Super Prep All-Farwest, Prep Star All-Western Region, Long Beach Press-Telegram Best in the West first team, Tacoma News Tribune Western 100, Orange County Register Fab 15 first team, Las Vegas Sun Super 11 first team, Cal-Hi Sports All-State second team, All-CIF Southern Section first team, All-CIF Division I first team, Los Angeles Times All-Southern California Lineman of the Year, Los Angeles Times All-Southern California first team, Los Angeles Times All-Southeast/South Coast first team Lineman of the Year and Long Beach Press-Telegram Dream Team first team honors as a senior offensive lineman at Poly High in Long Beach (Calif.). He had 38 pancake blocks in 2001.

As a junior in 2000, he was named to the Long Beach Press-Telegram Dream Team third team. He was a member of 3 Poly teams that went 39-1-1 and won 3 CIF Division I titles (he started 2 years). He didn't play football until his sophomore year in high school. Current Trojans Hershel Dennis and Darnell Bing also prepped at Poly.

As just a first-year freshman, Justice started 12 games (all but the opener against Auburn, in which he didn't play at all) at right offensive tackle in 2002 and did a marvelous job. He was named to the 2002 The Sporting News Freshman All-American first team, Scripps/Football Writers Freshman All-American first team, Rivals.com Freshman All-American first team and The Sporting News Freshman All-Pac-10 first team. He got his first start (at Colorado) on his 18th birthday, becoming USC's first true freshman to start on the offensive line since guard Travis Claridge and tackle Faaesea Mailo did so in 1996 against Notre Dame. After the season, he had arthroscopic surgery to repair a dislocating right shoulder.

Justice started for his second season on the right side as a sophomore in 2003. He was named to the 2003 All-Pac-10 honorable mention squad. He missed 2 games (Arizona State and Stanford) with an ankle sprain.

Justice was slated to start for his third season at right offensive tackle as a junior in 2004. But he was ineligible for 2004 spring practice and the 2004 season because of a student conduct violation (he did not attend USC during that time), so he redshirted.

Currently he is an American football offensive lineman who was selected by the Philadelphia Eagles in the second round (39th overall pick) of the 2006 NFL Draft.
